Here you see clearly how the upper spike to 182.70 was within a couple of ticks of the white dotted line I drew two days earlier (Thursday level).
Which just goes to show how important/helpful those price zones are. They are based on real information, i.e. the price at which the most of trades occurred during the time shown on the chart. Now on this particular chart we cannot see that prior action which is why I draw the white dotted horizontal rays which plot that price into the future where it serves as to pay close attention to.
